Low Voltage Transformer

A low voltage transformer is an electrical device that converts high voltage into lower voltage. Its main purpose is to convert high voltage power sources (such as 110V or 220V) into a lower and safer voltage (such as 12V or 24V) that is suitable for use. 120v to 12v transformer designed to provide stable voltage output and have advantages in terms of safety and efficiency.

The best outdoor lighting transformer should have reliable and stable voltage conversion, energy-efficient operation, overload and short circuit protection, waterproof and durable construction, multiple output options, and compliance with safety standards. The Gardenreet 12v ac transformer features a high-performance toroidal core, allowing for efficient and quiet operation. It has an IP65 weatherproof stainless steel metal casing and is ETL certified, making it a high-quality transformer on the market.

12v transformers are commonly used to provide power to low voltage equipment or systems, such as low voltage lighting systems, audio devices, and communication equipment. In outdoor landscape lighting systems, 120 to 12 volt transformers are typically used to convert grid voltage to a voltage suitable for low voltage garden lighting fixtures, ensuring their proper operation and safety.For instance, outdoor landscape lighting fixtures such as spotlights, pathway lights, well lights, and garden lights from Gardenreet require the use of low-voltage cables and are connected to a low-voltage transformer.

1. The wattage of the low voltage lighting transformer you need depends on the total wattage of the outdoor landscape lighting fixtures you plan to connect.
2. A proper load rate can ensure that the transformer operates within its normal working range and prolong its lifespan. Therefore, it is recommended not to exceed 80% of the transformer's capacity.
3. If you plan to connect more lighting fixtures in the future, you may consider purchasing a transformer with a higher capacity.
4. Consider the number of installation lines and choose multi tap transformer. Gardenreet outdoor low voltage transformer, for example, has at least 2 taps, and the higher the wattage, the more taps are available.

For example, if you have 20 spotlights, each with a 5W bulb, the total wattage is 100W, so you would need to purchase a 150 watt transformer.

1. You need to first calculate the total wattage of all the light fixtures currently installed on the transformer.
2. A proper load rate ensures that the transformer operates within its normal working range and extends its lifespan. Therefore, it is recommended not to exceed 80% of the transformer's capacity.
3. Subtract the total wattage already used from 80% of the transformer's capacity to determine the remaining capacity.
4. Ultimately, it depends on the wattage of the new light fixtures being installed. For example, if the remaining capacity is 100W and the wattage of the new light fixture is 5W, you can install up to 20 light fixtures.

You can achieve this by installing both a photocell and a timer on the transformer. The photocell senses darkness and the timer controls the running time. By setting the timer to activate from 17:00 to 24:00, and when the photocell senses sufficient darkness within this time range, the transformer will be turned on. Then at 24:00, the timer will automatically turn off the transformer. It's important to note that the photocell and timer need to be wired and configured properly, and it's recommended to consult with a professional electrician for accurate installation and setup.
